So my 2003 FX4 level II had started running very rough with loss of power etc, it felt like it was misfiring. Immediately went to auto zone and had them run the codes. They told me it was a small evap leak and tried to sell me a new gas cap which I declined because my gas cap looked fine. I then started inspecting the rest of the fueling system and really could not find anything obvious. I went ahead and replaced the fuel filter which likely needed replaced, but that made no difference. I then started looking at the PCV valve and discovered it was loose, it was basically just floating in the hole because the threads had broken. I purchased a new PCV valve and "glued" it securely into the hole with RTV. However, this was not the fix either, engine was still running very rough. So i took it back to Autozone and had them scan the computer again, but this time the code showing was for a misfire on cylinder 5, the small evap leak code was gone. After inspecting plugs and wires, it turns out the wire going to plug #5 was damaged so i went ahead and had new plugs and wires installed which solved the problem.
So to sum it up, I guess I had 2 issues, loose PCV valve which I suppose was causing the small evap leak code, and then the misfire on cylinder #5, I'm just not sure why the misfire code did not show up the first time when it was scanned, perhaps Autozone only read me the first code and failed to go any farther? Anyway, just figured I would put this out there in case it helps anyone.
